Mac Pro (Mid 2010) General Troubleshooting — Minimum Conguration Testing 33
2010-08-31
Minimum Conguration Testing
The following procedure can help you troubleshoot a “No Power” or other startup related
symptom.
The method gradually builds up the system from a minimum conguration and veries
expected behaviors at each step. This approach helps determine which modules function
together. The goal is to identify which module(s) cause a symptom to recur when they are
added. This method may also help you discover a loose or faulty cable or connector.
If you encounter unexpected behavior during a step, you shoul investigate the last module you
re-installed. Backtrack to the previous step, remove the last installed module, and re-verify the
expected behavior.
Note: Minimum conguration testing may not be practical for every repair. Refer to other
troubleshooting sections in this manual for additional direction.
